I’ve tried that and it doesn’t make any difference to me; It looks like the meta fields aren’t all set up unless you load the form in wp-admin then save it. I’m trying to find someway to replicate this entirely in code; Feels like need to replicate the setup when the form loads not just the save, but can’t get it.
Was there anything else you were doing in your function?
I create a post; update a couple of fields (some simple text, one a repeater) then call the acf/save_post action but there’s still nothing there when I pull back the post meta, until I load and save via the wp-admin user interface.
I read a post elsewhere saying that they were creating the JSON for the field structure and posting that but I’m not sure how to go about getting hold of that.
